EDWARD A. TUTTLE, OF BROOKLYN, NEIV YORK.

WARM-AIR REGISTER AND VENTILATOR.

Specification of Letters Patent No. 20,106, dated April 27, 18-58.

To all whom it may concern:

Be it known that I, EDWARD A. TU'r'rLE, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in the construction of Warm- Air Registers and Ventilators; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the marks or letters of reference thereon.

This invention consists in an improved article of manufacture, viz. a warm air register made as hereinafter described.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A frame or case B, is formed, at the bottom part of which the leaves or valves 1, 2, 3, are suspended by their pins or axes P, one pin at the central part of the ends of each leaf, and upon which they are balanced and allowed to vibrate about one quarter of a circle, or from the horizontal where they are closed, to the perpendicular where they are wide open. A front or top plate of open or fret work A, is secured upon the top edge of the frame which hides in a measure the valve part of the register when placed in the wall, and presents a finished ornamental appearance. It also serves to protect the leaves when the register is placed in the floor.

A perforated rod It, suspended upon the overhanging crank pins r, one for each leaf, connects the leaves all together in such man nor, that by turning one they are all made to turn in a corresponding direction.

Leaves, thus connected and made to operate, I denominate the blind valves, and are especially adapted to registers and ventilators requiring a great number of leaves as in those for fireplaces with narrow flues, or in the larger sizes of registers, such valves being more cheaply connected and fitted together tightly, and also better for controlling or directing the currents of air passing through them. The connecting rod It, is suspended along the ends of the leaves, where it is most hid from view, and where also the crank pins r, to which it is attached are more readily molded, and cast upon the leaves in working order.

In furnishing a device at the front or top part of the register, by which to operate the blind valves at the back, and-which shall combine in itself the requirements both of a register and ventilator in the various positions in which they are used, a horizontal vibrating center piece D, as shown, possesses advantages over all others, inasmuch as it is readily operated by the hand or foot, when placed in or near the floor, and is also suitable for attaching cords, by which to operate it when placed above reach in the side walls of dwellings, and that without any additional pieces or parts being req uisite in the latter case.

In order to combine in the same register, the advantages, both of such vibrating center and the blind valves, with greater simplicity and economy, the said center piece I), is made to operate the blind valves, by imparting its vibrations directly and first to one central leaf 2, by means of a finger or prong g, connected with the crank pin, 2?, upon the upper surface of said leaf. This leaf 2, then imparts its motion to the con necting rod R, which in turn is made there by to operate all the other leaves in a corresponding manner to the leaf 2. There fore, by turning the vibrating center D in one direction, the leaves are all thrown open in a similar direction, in a uniform manner. By turning it in the reverse direction the leaves are all similarly closed. The leaves standing and moving parallel with each other at all times. By attaching cords to either of the two opposite sides of the center D, at d, cl, the ventilator can be opened and closed when placed above reach in the side walls of dwellings.

I am aware that registers have been made with a horizontal vibrating center; and also that the blind valves have been used. I therefore do not claim either device. But I.am not aware that such vibrating center and a set of blind valves have been combined together in the same register, in the particular manner shown, that is, where such vibrating center is connected with, so as to impart motion first to one central leaf, when such leaf is made the medium through which to communicate a similar motion to all the other leaves, by being attached to a rod connecting the leaves together for that purpose, by which the peculiar advantages of the vibrating center and also of the blind valves are obtained and combined in the same register and ventilator with increased utility and economy in the construction and use of the same.

The difierent parts of the register are sethe top plate A, to the top of the frame. It

cured together by means of peculiar shaped side or end pieces C C, fastened in the register frame in a peculiar manner. These end is also formed with a ledge or step along the back part. The register frame B, is made with small lugs Z, Z, at the bottom and also with notches or recesses f f, at the corners.

The end pieceswhich are slightly longer than the distance between the two notches f, f, at either end-are inserted into their places from the inside, by sliding them side- Wise upon or over the small lugs or projections Z, Z, and under the notches f f. They are then secured against such sidewise or lateral movement, by a screw or rivet s in the slot 8 in the frame. They are thus pre vented from falling downward, rising upwvard, or slipping sidewise out of placein the frame, and are held securely to it. The pins or axes P, are previously inserted through their openings P,,before sliding the second end piece. into its seat. The leaves are thus securely held in their places in the frame independently of the top plate A, which latter, by being screwed to the end piece at c is also held firmly upon the frame, or can be unfastened and removed from the frame without displacing or disturbing the valves of the register.

I do not claim any feature seen in the device of W. GaCook, 18 18, S. P. Munson, 1853, or the patent of George Pollock, 1847', but

Having thus described my invention, I claim and desire to secure by Letters Patent, as an improved article of manufacture A warm air register, made as herein set forth, viz., the frame B B, having lugs Z, Z, and recesses f, f, and the end pieces C, provided with lugs 0, for the reception of screws 70, the ledge or step and openings 39, p, p, for the leaves, all substantially as shown, when combined with a mechanism for operating the leaves.
